The navicular bone appears relatively thinned showing mild collapse with marrow edema signal eliciting high STIR and low T1 signals. Associated patchy marrow edema signal is
also seen involving the tarsal bones (most evident at cuboid bone) and to less extent the bases of the metatarsal bones as well as talus and calcaneus bones
Minimal intertarsal joint effusion
